Going back to an older problem...

I'm installed both RH 7.1 and Drake 8.0...

both install fine, and recognize my NIC(they even tell me the name). Both set themselves to determine my IP during boot.

And both, also give me this error:

"eth0 ..... Determining IP FAILED!!!"

no clue why... help....please?

[lilrabbit129]

oops forgot to mention that it's supposed to determine my Ip through DHCP...

and yes they are set that way

I use static IPs on my internal network, but a lot of previous posts have dealt with DHCP configuration problems. Try browsing past threads on the subject by using the Forum Search (http://www.linuxnewbie.org/cgi-bin/ubbcgi/ultimatebb.cgi?ubb=search). As keywords, try "dhcp" "dhcpd" and "pump". Searching all of the forums (the default) takes forever; your best bet is to search "Networking" first. If archived threads in that forum don't give you an answer, search the "General Linux Questions" and "Technical Support" forums.

I have the same eth card, and cable modem through AT&T, DHCP. I am using RH6.2, only difference. You have made certain that the cable provider has your nic ID in his database, of course, if required. AT&T requires this. Try this as root: pump -i eth0
There should be a few seconds of furious blinking, and then pump -s should show you the work that got done, IP, DNS boxes, gateway, etc. Read the man pages on pump. it's very capable.

I probbaly should have mentioned that it's throught a campus network.

And we have to dynamically receive an IP using DHCP.

But the problem seems to be, that for some reason RH can't bring up eth0 interface.

Example: I went to "Network Configuration" and tried to "activate" eth0. But once i click that button, Network Config seems to just freeze. I have to kill the process and select it again, but once i get back into Network Config, it shows eth0 as active..

my theory is that it does something similar during boot...

any help?

I suppose that you have only one NIC in your computer:

1. Look carefully when redhat starting up, do you see something like "bring up eth0(or eth1)". This will give you an idea which eth is working or not.

2. Once you get into redhat, as root, type the command "ifconfig", if you get both ethx and "lo" then your networking setup is pretty good and it probalby will work. If not, please post what happens.

During boot, "Bringing up eth0" takes a while then says Operation failed.

I tried "ifconfig" once i get into RH. I only see and entry for lo, no eth0.

and also when i tried the suggestions

"pump -i eth0"... it sat there for a while then said "operation failed"

try something like this:

1. login as root then type "netcfg", the hit the tab "interface", then see if there is an eth0 line. If there is, then hit "edit". Select "Activate interface at boot time" and select interface configuration protocole as dhcp. Then hit "activate" .Then save and quit.

2. Type the command "/etc/rc.d/intit.d/network restart"
if it works, you should see a print out "bring up eth0 [ok].

3. Type "ifconfig" to see if there is a line with eth0. If yes, then you can try the internet.
